[19p-143-6] Synthesis and growth of Sr2Can-1CunOy superconductor crystals which high-pressure synthesis method
Keywords:superconductor, single crystal, high pressure synthesis
The 02(n-1)n series of the Sr-Ca-Cu-O system has been investigated by various groups.
The discovery of 02(n-1)n (n=2-4) in the Sr-Ca-Cu-O system has become an important clue to derive the concept of the homologous series.
In the previous study, The characteristics of this superconductors upgraded the Jc property by entering water between the SrO planes, but the critical temperature of this superconductors almost unchanged. However, crystal structure of this superconductors is unknown.
Therefore, as a method of study of crystal structure analysis, 02(n-1)n crystals are synthesized and grown by using the cooling method and verified examination of crystals growth conditions.
